	117	+* Precharge current threshold to close the discharging contactor – a current value to ensure that precharge process has finished and it is allowed to close the discharging contactor, A;
	118	+* Check voltages before and after contactors to finish precharging – a flag to check the voltages before and after contactors to ensure that precharge process has finished and it is allowed to close the discharging contactor;
	119	+* Minimum voltage difference before and after contactors to finish precharging – a minimum voltage difference before and after contactors to ensure precharge process finished, V;
	120	+* Number of precharging attempts – maximum number of precharging attempts before setting the "Precharge error";
	121	+* Delay before current measurement – a delay before first current measurement after closing precharge, millisecond;
	122	+* Precharge time – a duration of closing the precharge contactor before closing the discharging contactor, millisecond;
	123	+* Relaxation between attempts – a duration between precharge attempts, millisecond;
	124	+* Check the power dissipated in the preacharge resistor - a flag to enable the calculation of power dissipated in precharge resistor;
	125	+* Precharge resistor resistance, Ohm;
	126	+* Maximum allowable power dissipated in the resistor, W;
	127	+* Delay before setting the "Precharge error" when checking power, millisecond;

	131	+“Precharge error” generation conditions if any of the following is true:
	132	+
	133	+* the precharge current does not decrease during the "Precharge time" after "Number of precharging attempts";
	134	+* voltages before and after contactors are not equal during the "Precharge time" after "Number of precharging attempts";
	135	+* power dissipated on the precharge resistor is above the maximum value during the “Delay before setting the 'Precharge error' when checking power” time.
